How to Start Season of Hell’s Legacy in Diablo 4 comes down to entering the Seasonal realm after Season 15 goes live and following the new seasonal questline. You can create a new Seasonal character as usual, or use the new Rebirth feature to move an eligible Eternal character into the season while resetting it to level 1.
The important part of How to Start Season of Hell’s Legacy in Diablo 4 is that Rebirth is optional. You do not need to sacrifice an Eternal character to play Season 15, and you do not need to finish a complicated unlock chain before the seasonal story appears. Rebirth is simply a way to keep a character’s identity while starting the seasonal progression from level 1.

After the 9:30 a.m. PT rollout begins, update Diablo IV and select the Seasonal realm when making your character. If you are using Rebirth, clear that Eternal character’s equipped gear and personal inventory first. Blizzard will not let the conversion proceed while the character is still carrying items, which prevents valuable equipment being deleted by accident.
Once you are in the Seasonal realm, How to Start Season of Hell’s Legacy in Diablo 4 means following the Season of Hell’s Legacy quest prompts rather than heading straight into random endgame farming. The seasonal questline introduces the three dark wanderers and eventually takes you into the Prime Evil memories tied to Diablo, Baal and Mephisto.
Why the seasonal questline matters
The quest is not just story dressing. How to Start Season of Hell’s Legacy in Diablo 4 properly means progressing far enough to collect the three Prime Evil Splinters of Evil. Those powers determine which reputation track you are building and which activities receive seasonal modifiers through your War Plans.
Diablo’s Splinter of Terror is linked to Helltide and Infernal Hordes, Baal’s Splinter of Destruction to The Undercity and Lair Bosses, and Mephisto’s Splinter of Hatred to The Pit and Nightmare Dungeons. All three interact with Tree of Whispers content, so the choice changes how you approach the season once the introductory chain opens up.
New character or Rebirth?
For most players, How to Start Season of Hell’s Legacy in Diablo 4 is equally straightforward with either route. A brand-new character is the cleanest option if you want a fresh name or appearance. Rebirth is better if you are attached to an existing character and want its identity and total-hours history to continue across seasons.
Rebirth keeps class, name, appearance and Normal or Hardcore state, and cosmetic preferences can transfer when they are saved as part of an ensemble. It does not carry your combat power into Season 15. The character resets to level 1, which is why a strong Season 15 leveling setup still matters even when you use Rebirth.
What to focus on after the introduction
Once How to Start Season of Hell’s Legacy in Diablo 4 is out of the way, start building your Season Ranks and learn the two different Splinter systems. Prime Evil Splinters govern your alignment and activity modifiers; Soul Splinters are socketable seasonal gems placed in Jewelry. Treating those as the same item is an easy way to make the season look more confusing than it is.
